Cell-level/call-level ATM switch simulator

A B-ISDN national project in Korea has been carried out to develop a Nation al Information Superhighway since 1992. An ATM switching system has been de veloped as one of the most important parts in the project, and has been tes ted in the National Information Superhighway testbed. In this paper, we dev elop a cell-level/call-level ATM switch simulator using cell-level and call -level input traffic models for evaluating the ATM switching system. The ce ll-level simulator models various cell-level switching functions such as pr iority control and multicast, and evaluates the cell-level performance indi ces of the ATM switch in terms of cell delay, throughput, and cell loss pro bability. On the other hand, the call-level simulator uses call-level traff ic models and evaluates the call blocking rate as a call-level quality of s ervice (QoS).
